UPDATE: The U.S. Department of the Treasury has officially announced the changes coming to the $5, $10, and $20 bills. As anticipated, the new $20 bill will feature Harriet Tubman on the front, with the White House and former president Andrew Jackson on the back; the $10 bill will maintain Alexander Hamilton's image on the front and celebrate leaders of the women's suffrage movement—like Lucretia Mott, Sojourner Truth, Susan B. Anthony, Elizabeth Cady Stanton, and Alice Paul—on the back; and the $5 bill will keep Abraham Lincoln on the front while showcasing Martin Luther King, Jr., Marian Anderson, and Eleanor Roosevelt on the back. The Treasury Department has directed people to its new Modern Money site for more information on the updated currency.

It's been a long journey to get here, but ladies, we've finally arrived: Today the U.S. Department of the Treasury is reportedly planning to announce that a woman will grace the $20 bill. And not just any woman—Harriet Tubman. Though there was some initial talk about a woman (likely Susan B. Anthony) replacing Founding Father Alexander Hamilton on the $10 bill, Treasury Secretary Jack Lew is rumored to be making a statement later today revealing that abolitionist Harriet Tubman will be replacing former president Andrew Jackson on the $20 bill, instead.

Right now, this news is only a rumor (originally reported by Politico), and the Department of the Treasury has yet to make a statement about it. Still, sources reportedly told Politico that Lew will be announcing a slew of currency changes later today, including: including notable figures from the women's suffrage movement on the back of the $10 bill, putting notable figures from the civil rights movement (and other important moments in our country's history) on the $5 bill, and, of course, adding Tubman to the $20 note. It's worth acknowledging that these same sources said Jackson would likely remain on the $20 bill—he'll just be moved to the back.

"When we started this conversation not quite a year ago, it wasn't clear to me that millions of Americans were going to weigh in with their ideas," Lew told CNBC last week. "We're not just talking about one bill. We're talking about the $5, the $10, and the $20. We're not just talking about one picture on one bill. We're talking about using the front and the back of the bill to tell an exciting set of stories." This statement is in congruence with the rumors coming out of Politico today, but another portion of the interview raises questions about the rumor's credibility.

"We're going to have a representation of the contribution women have made to our democracy on the next bill that's issued, and that's going to be the $10," Lew told CNBC. The interviewer responded, "So woman on the front, Hamilton on the back." "I'm not saying who's where or what's where," Lew said. "But it's an exciting—we're going to have an exciting set of announcements." This exchange doesn't necessarily contradict the rumor (leaders of the women's suffrage movement are said to appear on the back of the $10 bill, after all), but it does serve to remind readers that these rumors are just that—rumors. We'll have to hold off until later today to get Lew's official announcement on the matter.

If Tubman does come to replace Jackson on the $20 note, that will signify a huge advance in terms of gender and racial equality. When Lew first suggested swapping Hamilton from the $10 bill for a woman last year, many suggested he consider removing Jackson from the $20 bill, instead, due to the former president's history with slavery and discrimination against Native Americans. By replacing this figure with a Harriet Tubman—a former slave who served as a leader in both the abolitionist and women's suffrage movements—the Treasury Department is giving widespread recognition to an American hero who has often gone unnoticed due to her race and gender.

More information is to come later today when Lew makes his much-awaited announcement.
